I owned a similar yellow jacket from Pearl Izumi which fit well and was extremely durable (3 years, 5 mornings a week). This jacket has the same fit and will, I assume, also last for several years. I am 5' 10" 190 lbs. and the large size jacket is snug but comfortable over a light-weight fleece, perfect for riding my bike in temperatures 40 to 55 degrees. It is not waterproof but I didn't expect it to be. Until someone convinces me otherwise, I am going to stick with the Pearl Izumi jackets.

this jacket is very good at keeping the chill of the morning commute off. It also allows moisture to escape. This coat is not water proof. No coat can ventilate and keep you waterless. Take your pick. This coat is also very visible. Just what you want in dark conditions.

What with the low light and cold temps of winter, this jacket seemed to be a good bet for winter riding. It is. Light weight, you think to yourself "How is this gonna keep me warm?" It's got a lot of ventilation around the armpit area. With a good breathable base layer, this thing works way better than you'd think. The wind doesn't penetrate, and when you work up a sweat, you vent it quickly, so no soggy/clammy feeling. I'd think, for temps below 35 degrees or so, you'd need a wool sweater of something else besides a base layer. I ordered the extra large, and for me the torso length is a bit too long...it made for some awkward exits the 1st couple of times, because the tail caught over the back of my saddle. I've learned to cinch it up or tuck it in (dorky, who cares, I already look like a dork), and that caveat notwithstanding, I'm very pleased. Recommended. Get a balaclava, some decent winter gloves, you're set for winter riding.

Love this jacket. I am 6', 185 lbs and it fits perfectly. Good quality and works well on chilly fall rides. I haven't worn in the rain yet, so I can't speak to the water resistance, but the material seems light and not as water proof as a rain jacket.
